A packet received on a trunk will have bit 2 set in Forward DSA tagged frame. Bit 1 can be either 0 or 1 and is otherwise undefined and bit 0 indicates the frame CFI. Masking with 7 thus results in frames as being identified as being from a trunk when in fact they are not. Fix the mask to just look at bit 2.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net (v2) The following patchset contains Netfilter fixes for net: 1) Move back the defrag users fields to the global netns_nf area. Kernel fails to boot if conntrack is builtin and kernel is booted with: nf_conntrack.enable_hooks=1. From Florian Westphal. 2) Rule event notification is missing relevant context such as the position handle and the NLM_F_APPEND flag. 3) Rule replacement is expanded to add + delete using the existing rule handle, reverse order of this operation so it makes sense from rule notification standpoint. 4) Propagate to userspace the NLM_F_CREATE and NLM_F_EXCL flags from the rule notification path. Patches #2, #3 and #4 are used by 'nft monitor' and 'iptables-monitor' userspace utilities which are not correctly representing the following operations through netlink notifications: - rule insertions - rule addition/insertion from position handle - create table/chain/set/map/flowtable/... ==================== Signed-off-by: -

Commit 2d26f6e3 ("net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings") while getting rid of a runtime PM warning ended up breaking ethernet on rk3399 based devices. By dropping an extra reference to the device, the commit ends up enabling suspend / resume of the ethernet device - which appears to be broken. While the issue with runtime pm is being investigated, partially revert commit 2d26f6e3 to restore the network on rk3399.

When ocelot_flower.c calls ocelot_vcap_filter_add(), the filter has a given filter->id.cookie. This filter is added to the block->rules list. However, when ocelot_flower.c calls ocelot_vcap_block_find_filter_by_id() which passes the cookie as argument, the filter is never found by filter->id.cookie when searching through the block->rules list. This is unsurprising, since the filter->id.cookie is an unsigned long, but the cookie argument provided to ocelot_vcap_block_find_filter_by_id() is a signed int, and the comparison fails.

Syzbot reported memory leak in MDIO bus interface, the problem was in wrong state logic. MDIOBUS_ALLOCATED indicates 2 states: 1. Bus is only allocated 2. Bus allocated and __mdiobus_register() fails, but device_register() was called In case of device_register() has been called we should call put_device() to correctly free the memory allocated for this device, but mdiobus_free() calls just kfree(dev) in case of MDIOBUS_ALLOCATED state To avoid this behaviour we need to set bus->state to MDIOBUS_UNREGISTERED _before_ calling device_register(), because put_device() should be called even in case of device_register() failure.

This reverts commit ab609f25. This patch is correct in the sense that we _should_ call device_put() in case of device_register() failure, but the problem in this code is more vast. We need to set bus->state to UNMDIOBUS_REGISTERED before calling device_register() to correctly release the device in mdiobus_free(). This patch prevents us from doing it, since in case of device_register() failure put_device() will be called 2 times and it will cause UAF or something else. Also, Reported-by: tag in revered commit was wrong, since syzbot reported different leak in same function. Link: https://lore.kernel.org/netdev/20210928092657.GI2048@kadam/Acked-by:

The value for maximum number of channels is first calculated based on the netdev's profile and current function resources (specifically, number of MSIX vectors, which depends among other things on the number of online cores in the system). This value is then used to calculate the netdev's number of rxqs/txqs. Once created (by alloc_etherdev_mqs), the number of netdev's rxqs/txqs is constant and we must not exceed it. To achieve this, keep the maximum number of channels in sync upon any netdevice re-attach. Use mlx5e_get_max_num_channels() for calculating the number of netdev's rxqs/txqs. After netdev is created, use mlx5e_calc_max_nch() (which coinsiders core device resources, profile, and netdev) to init or update priv->max_nch. Before this patch, the value of priv->max_nch might get out of sync, mistakenly allowing accesses to out-of-bounds objects, which would crash the system. Track the number of channels stats structures used in a separate field, as they are persistent to suspend/resume operations. All the collected stats of every channel index that ever existed should be preserved. They are reset only when struct mlx5e_priv is, in mlx5e_priv_cleanup(), which is part of the profile changing flow. There is no point anymore in blocking a profile change due to max_nch mismatch in mlx5e_netdev_change_profile(). Remove the limitation.

Currently in Rx data path IPsec crypto offloaded packets uses csum_none flag, so checksum is handled by the stack, this naturally have some performance/cpu utilization impact on such flows. As Nvidia NIC starting from ConnectX6DX provides checksum complete value out of the box also for such flows there is no sense in taking csum_none path, furthermore the stack (xfrm) have the method to handle checksum complete corrections for such flows i.e. IPsec trailer removal and consequently checksum value adjustment. Because of the above and in addition the ConnectX6DX is the first HW which supports IPsec crypto offload then it is safe to report csum complete for IPsec offloaded traffic.

Jann Horn reported that SO_PEERCRED and SO_PEERGROUPS implementations are racy, as af_unix can concurrently change sk_peer_pid and sk_peer_cred. In order to fix this issue, this patch adds a new spinlock that needs to be used whenever these fields are read or written. Jann also pointed out that l2cap_sock_get_peer_pid_cb() is currently reading sk->sk_peer_pid which makes no sense, as this field is only possibly set by AF_UNIX sockets.

When STMMAC is paired with Energy-Efficient Ethernet(EEE) capable PHY, and the PHY is advertising EEE by default, we need to enable EEE on the xPCS side too, instead of having user to manually trigger the enabling config via ethtool. Fixed this by adding xpcs_config_eee() call in stmmac_eee_init().

struct dev_addr_list is used for device addresses, unicast addresses and multicast addresses. The first of those needs special handling of the main address - netdev->dev_addr points directly the data of the entry and drivers write to it freely, so we can't maintain it in the rbtree (for now, at least, to be fixed in net-next). Current work around sprinkles special handling of the first address on the list throughout the code but it missed the case where address is being added. First address will not be visible during subsequent adds. Syzbot found a warning where unicast addresses are modified without holding the rtnl lock, tl;dr is that team generates the same modification multiple times, not necessarily when right locks are held. In the repro we have: macvlan -> team -> veth macvlan adds a unicast address to the team. Team then pushes that address down to its memebers (veths). Next something unrelated makes team sync member addrs again, and because of the bug the addr entries get duplicated in the veths. macvlan gets removed, removes its addr from team which removes only one of the duplicated addresses from veths. This removal is done under rtnl. Next syzbot uses iptables to add a multicast addr to team (which does not hold rtnl lock). Team syncs veth addrs, but because veths' unicast list still has the duplicate it will also get sync, even though this update is intended for mc addresses. Again, uc address updates need rtnl lock, boom.

Patch that refactored fl_walk() to use idr_for_each_entry_continue_ul() also removed rcu protection of individual filters which causes following use-after-free when filter is deleted concurrently. Fix fl_walk() to obtain rcu read lock while iterating and taking the filter reference and temporary release the lock while calling arg->fn() callback that can sleep.

This patch addresses the issue introducing a nested variant of lock_sock_fast() and using it in the relevant code path.

Per gpio_chip interface, error shall be proparated to the caller. Attempt to silent diagnostics by returning zero (as written in the comment) is plain wrong, because the zero return can be interpreted by the caller as the gpio value. Cc: stable@vger.kernel.org Signed-off-by:

Pull sound fixes from Takashi Iwai: "This became a slightly large collection of changes, partly because I've been off in the last weeks. Most of changes are small and scattered while a bit big change is found in HD-audio Realtek codec driver; it's a very device-specific fix that has been long wanted, so I decided to pick up although it's in the middle RC. Some highlights: - A new guard ioctl for ALSA rawmidi API to avoid the misuse of the new timestamp framing mode; it's for a regression fix - HD-audio: a revert of the 5.15 change that might work badly, new quirks for Lenovo Legion & co, a follow-up fix for CS8409 - ASoC: lots of SOF-related fixes, fsl component fixes, corrections of mediatek drivers - USB-audio: fix for the PM resume - FireWire: oxfw and motu fixes" * tag 'sound-5.15-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (25 commits) ALSA: pcsp: Make hrtimer forwarding more robust ALSA: rawmidi: introduce SNDRV_RAWMIDI_IOCTL_USER_PVERSION ALSA: firewire-motu: fix truncated bytes in message tracepoints ASoC: SOF: trace: Omit error print when waking up trace sleepers ASoC: mediatek: mt8195: remove wrong fixup assignment on HDMITX ASoC: SOF: loader: Re-phrase the missing firmware error to avoid duplication ASoC: SOF: loader: release_firmware() on load failure to avoid batching ALSA: hda/cs8409: Setup Dolphin Headset Mic as Phantom Jack ALSA: pcxhr: "fix" PCXHR_REG_TO_PORT definition ASoC: SOF: imx: imx8m: Bar index is only valid for IRAM and SRAM types ASoC: SOF: imx: imx8: Bar index is only valid for IRAM and SRAM types ASoC: SOF: Fix DSP oops stack dump output contents ALSA: hda/realtek: Quirks to enable speaker output for Lenovo Legion 7i 15IMHG05, Yoga 7i 14ITL5/15ITL5, and 13s Gen2 laptops.

When EEE support was added to the 28nm EPHY it was assumed that it would be able to support the standard clause 45 over clause 22 register access method. It turns out that the PHY does not support that, which is the very reason for using the indirect shadow mode 2 bank 3 access method. Implement {read,write}_mmd to allow the standard PHY library routines pertaining to EEE querying and configuration to work correctly on these PHYs. This forces us to implement a __phy_set_clr_bits() function that does not grab the MDIO bus lock since the PHY driver's {read,write}_mmd functions are always called with that lock held.

Currently, the firmware compatible features are enabled in PF driver initialization process, but they are not disabled in PF driver deinitialization process and firmware keeps these features in enabled status. In this case, if load an old PF driver (for example, in VM) which not support the firmware compatible features, firmware will still send mailbox message to PF when link status changed and PF will print "un-supported mailbox message, code = 201". To fix this problem, disable these firmware compatible features in PF driver deinitialization process. Fixes: ed8fb4b2 ("net: hns3: add link change event report") Signed-off-by:
